A new app for iOS called Krisp uses machine learning technology to filter out all kinds of background noise on your end while making voice calls. It can completely filter out background sound such as nearby conversations, screaming kids, barking dogs, coffee machines, air conditioners, etc. It offers calendar integration for easily joining conference calls, including Zoom, Webex, Hangouts, and more. It works as an alternate dialer, used in place of the built-in Phone app in iOS. The app is free to download from the App Store and offers up to 240 minutes of free noise-free calls per week.
